Issue in MongoDB node module

[kirill-tolochko]

Problem description

In some cases there is an error in mongodb node module

Step to reproduce

Steps to reproduce the behavior:

1. Import Verra\Verra Redd\VM0044 policy
2. Run it in dry run, create Project_proponent user, create project, add it by administrator
3. Create VVB user, assing created project to this user
4. Check status history and console of policy service

Expected behavior

Waiting for validation should be presented 2 times (or 1?)

Actual behavior

Now "Waiting for validation" is presented 3 times. 1 time right after it was added by administrator, and 2 times after it was assigned to VVB.

Also there is an error in the policy service console:

Now there are only 2 "waiting for validation" messages, that's ok.

Fixed partially, duplicate events are a special case. Issue may occur when we are trying to update documents in parallel threads and it requires a more complex solution.
